Renfree (6-3, 219) succeeded Thad Lewis under center at Duke and started three seasons for QBs guru David Cutcliffe, completing 64.7 percent of his throws with a 50:40 TD-to-INT ratio. Renfree tore the pectoral muscle in his right (throwing) arm in the Blue Devils' bowl loss to Cincinnati, but should be ready for camp. He's drawn Matt Hasselbeck and Matt Schaub comparisons as a heady if modest-armed passer with accuracy and anticipation. Rotoworld draft columnist Alen Dumonjic studied Renfree on tape and believes he could grow into an NFL starter. Developing behind Matt Ryan will be a big plus. Sat, Apr 27, 2013 07:21:00 PM

Mayock pegged North Carolina's T.J. Yates as his sleeper quarterback before the 2011 draft. "He hurt his shoulder on the last snap of their bowl game and might not even get drafted," Mayock said of Renfree. "But he’s got the best anticipation and timing of any quarterback in this draft. Part of it is because he’s got an average arm and has to. (Duke coach) David Cutliffe told me that Sean approaches the game with a work ethic and passion similar to Peyton Manning’s."
